wma-mienne MACHINE.

`Be it known that I, GUNNAR EMANUEL EHRLINc,-a citizen of the UnitedStates, residing at Chicago, in the county of Cook l*and "fiStateofIllinois, have invented .a certain vnew and useful Improvement inWire-Twist- -ing Machines, of which. the following is a means fortwisting a wire for lubricating such specification.

My invention relates toimprovements '1n wire twisting means, and has forsome of lts objects lto provide a ne'nf` and improved tieabout the neckAof a bag or other pgckage; to provide means 'twisting means; tominimize the wear on the 'twisting means, land to inclo'se Vall theworking-parts in an oil casing.

The invention is illustrated more vor less 'diagrammatically the.accompanying drawings, whereinf-l i '-with cover removed; Fig; Qis "asection on the Vline 2-2of Fig. 1 with cover in place; Fig. 3 is alongitudinal v,section through a modified form showing'my'inventionapplied to a hand'tool; Fig. 4'is a section on the une 4 4 of Fig. a.

Like parts are llndica'ted by like letters throughout the severaligures.

Referring irst to the bench in Figs. 1`and'2, along rectangular boi: Ais divided by a transverse partition A-1 into a spring chamber A? andtwisting chamber A3. TheA rod- Ai passes through the partition A1 andthe end wall Als of the box, said end wall being provided with astuiiing box A6. Y Y -v is a twisting head on the outer end of the rodand from it project outwardly the twisting spring ngers AB having hooksA9 in their lends to 'engage the tie A1 which is to be twisted abouttheneck of the bag A11.

long rack B1 inthe chamber A.

B is a short'worm or helical gear `rigidly mounted on the rod A4 and inmesh with a is located beneath the rod though' in mesh with the gear sothat a longitudinal movement of the rod ,will cause its rotation byvirtue of the interlockingof the rack and WOIIII.

. In o rder to provide means for adjusting the twist given'to 'the wire,it is only necessary to limit the longitudinal movement of the rodbecause the number of twists bear direct relation to the distance therod is` moved. In order lto provide for this the .inside wall of thechamber A3 is provided 1n the preferred form with three notches, C, C1,C2 and in one of these notches is llocated a stop plate'C4 notched asindicated to pass over and straddle the rod and pro-4 ]ect downproviding a Istop against which the gear B may impinge. It will beunderstood that this stop is held in place by the cover and when that isremoved the stop -plate may be withdrawn or placed in any one ofl thenotches at the will 'of the oper? ator; The lugs C5 are provided so thatthe box maybe bolted orotherwise fastened to a work bench or table.

In the hand form shown in Figs. 3 and 4, the hollow handle D is providedat its smaller end with a bearing sleeve D1 and stuffing box Dzifor therod D3, the rod having on the end the wire twisting means D4. Access tothev interior of the hollow handle is obtained by` means of thescrew-threaded plug E and in this hollow interior is' located a shortworm 'or helical gear El on the inner end of the rod D3.V This gear is.in mesh with a lon rack E2 held in position on the handle the screws E3(The rack is shown as semi-circular in cross section so as to make itconform with the inlterior of the handle. No spring-is here-"providedIl'tvill be understood that the rod D is stift, and the bearingl)1guides and holdsit in position; and it is this stiifnessof the rod a dthis tubular b'earing D1 which come bin 'to hold the gear E1 in meshwith the rad? E?. This combination is possible only of ourse owing tothe shortness and rela-V tive rigidity and heaviness of the rod.

Q Icourse it will be understood that I do not wish to be'limited to the'precise forms,
